Title: Ignition system for internal combustion engine
Inventor: OGAWA TOMOYUKI
IPC: F02P5/155
Filed: 1993-02-19
Abstract: PURPOSE:To achieve the characteristic of spark advance again after an ignition position is once delayed at a predetermined rotational frequency by comparing between first and second integrated voltages to generate a delay angle position setting signal, by comparing the setting signal with third integrated voltage, and thereby having the ignition position delayed at a desired rotational frequency. CONSTITUTION:When the rotational frequency, at which an ignition position spark- advances to a maximum spark advance position theta1 at a spark advance rotational frequency N1, reaches a delay rotational frequency N2, the integrated voltage V.c5 falls to no greater than a specific voltage Vo. The output terminals of comparators CM4, CM3 are grounded, and the output of a spark advance ignition command signal Vt1 is inhibited. Since a third integrated voltage Vc3 falls to no greater than a delay ignition position signal Vr at a delay ignition position theta2, a delay ignition command signal Vto is generated, and an ignition signal Vi is given to a thyristor 106, causing delay. When the rotational frequency reaches a second spark advance rotational frequency N3, a sixth integrated voltage Vc6 falls to no greater than a spark advance band signal Viw at the maximum spark angle position theta1, generating a spark advance ignition signal Vt2 due to electrification of PUT. Spark advance is thus achieved in step.

Abstract: PURPOSE: To make a tone arm light-weight and improve the reproducing characteristic by fixing a surface material consiting of high-specific modulus materials to the outside circumference of a pipe-form core material consisting of a prescribed low-density material through radial beams.  
     CONSTITUTION: Pipe-form core material 1 is formed by Al, Mg, their alloy, or synthetic resin whose specific gravity is 3 or less, and radial beams 2 have plural one-side end face parts caused to adhere to the outside circumference of core material 1 by adhesive 5. Meanwhile, reinforcement beams 4 arranged between the radial beams 2 above are fixed to radial beams by adhesive. Surface material 3 on the outside circumference of radial beams 2 consists of a low-density and high- specific modulus thin film.

Abstract: PURPOSE:To decide the success/failure of transmission depending on a signal itself not on the operation of a transmission system existing in midway by using an alternate signal for a command itself inputted to the transmission system and detecting its frequency at the reception side. CONSTITUTION:Commands Xi and Ai-Ci are sent to the transmission line 3 via a microcomputer 12 and a transmission control section 13. A receiver 2 uses a transmission control section 23 and a microcomputer 22 to output a command data to an output buffer 21 thereby obtaining output Xtheta and Atheta-Ctheta. In case the input of the command Xi is connected to an output of an oscillator 5, it is specified as the danger side and in case the command is connected to 0V, it is specified as the safety side command. Then an alternate signal output of a prescribed frequency is obtained as Xtheta to the danger command so long as the entire transmission system from an input buffer 11 to an output buffer 21 is normal. Thus, fail safe transmission is realized to the command Xtheta.

SOLUTION: When a combine comes into a levee edge control region, a controller begins to slowly ad just a plucking out depth-adjusting means (e.g. a supplying reaper) from the position of a common plucking out depth to the side of a deeper plucking out position since before short hollow stems are detected, increases a moving velocity for the adjustment depending on the increase of cutting height, continuously adjusts to the side of deeper plucking out for a cutting height in stopping reaping, while, when short hollow stems are detected by a detecting means (e.g. a short hollow stem-detecting sensor S3) for cereal hollow stem lengths, the controller can immediately adjust the depth-adjusting means to the deepest plucking out position.  A threshing machine can thresh in a suitable plucking out depth and suitably carries out separation and selection, thus, it becomes to be able to improve efficiency of cereal grain- recovery, reduce discharge straws and prevent thresher disorders by plugging, and so forth.

Title: Operation display panel
Inventor: KAWASAKI KIKUO
IPC: G09G3/00
Filed: 1990-02-14
Abstract: PURPOSE:To improve the safety without decreasing the operability by classifying transparent switches into a direct output type and an indirect output type and making their display methods different. CONSTITUTION:The switches are classified into direct output type switches which generate outputs through their individual operation and indirect output type switches with generate outputs in cooperation with switches for output generation. The switches are displayed by mutually different methods. When a transparent switch is operated in a step S1, it is judged whether or not an execution key needs to be operated in S2 according to the contents of function settings. When a switch which requires key operation is operated, the selection state is stored in S3. Then the switch makes a display by blinking to prompt operation and a control output is generated in response to the operation of the execution key. When the execution key need not be operated, the operation of the transparent switch is displayed effectively throughout the operation and a control output is generated. Consequently, the switches are securely operated and the safety is improved without decreasing the operability.

Abstract: PURPOSE:To easily stop a sewing needle at a desired position by rotating two motors which drive a needle bar and a hook at high speed in regular sewing, and rotating them at slow speed when a needle upward/downward motion input means is operated. CONSTITUTION:When a slow forward rotating switch 29 or a slow backward rotating switch 30 is operated, the sewing needle is moved upward/downward, and also, since slow operating speed is applied, the sewing needle can be easily stopped at the desired position. Also, since the motor 24 for upper shaft which moves the sewing needle 17 upward/downward, the motor 10 for lower shaft which rotates a hook 8, and the motor 14 for feed which drives a feed dog 7 are rotated based on a volume corresponding to the volume of rotation of the motor 24 for upper shaft, no unmatching of position relation among the feed dog 7, the hook 8, and the sewing needle 17 occurs. Therefore, a regular sewing operation in which needle thread is inserted to a loop formed on bobbin thread 19 by the operation of the sewing needle 16 and, while, by the operation of the hook 8 can be performed normally. Also, when the regualr sewing is started by turning on a start-up/stopping switch 28, a controller 27 drives the motor 10, 14, and 24 at high speed via a driving circuit 31.

Abstract: PURPOSE:To improve the efficiency of communication by informing a data processor that the circuit quality of a communication circuit selected at a controller having a communication controller provided between the data processor and communication circuit does not meet requirements designated by the processor. CONSTITUTION:A controller, once informed of communication at a speed higher than an S2 by a data processor after a communication circuit is selected between the processor and a terminal equipment, discriminates whether the selected circuit is capable of communication at the speed by using a speed setting circuit 1 and a quality measuring circuit 2; when its circuit quality does not satisfy prescribed one, a speed reduction infication signal is sent from the quality measusing circuit 2 to the speed setting circuit 1 to reduce the speed of the circuit to a slow speed S2 and also to send information on the speed S1 to a comparing circuit 3. The circuit 3 compares the speed S1 with the reported S2 and, when S1<S2, sends NG information to the processor. When resetting and a communication speed higher than the S2 are indicated from the processor, whether communication is possible at a speed S3 or not is discriminated and when it is possible, the communication at the speed is started.
